I've worked it out now. Your image is far, far deeper. Consequently your nebulosity extends out much further, and covers or obscures a number of stars which are showing as way outside the nebula in the ESO image. Wasn't trying to play silly buggers, I just couldn't make the patterns match up. Now with fresh eyes, it's obvious. What the big fellows did wrong was to clip their data.

Best,
Mike
